Rules and Guidelines

All tournaments will be run following the Double Elimination format. This means that you can lose one match, after which you will be demoted from the starting bracket (Winners’ Bracket) to Losers’ Bracket. A loss in Losers’ Bracket will knock you out of the tournament, but if make it to the end of the bracket undefeated, you will advance to Grand Finals, where the winner will be declared the champion!

All matches (excluding Finals) will follow Best of 3 format, meaning that the first player to win two games in a match is deemed that winner of that match.

Winners’ Finals, Losers’ Finals, and Grand Finals will follow Best of 5 format, where players must win three games to win the match.

Players are highly encouraged to bring their own controllers, but there are controllers available to rent for free in the game room. Anyone who makes it all the way to Top 3 will receive prizes. Every tournament will be streamed on and all replays of streamed matches will be uploaded on the OffKai Expo YouTube channel.

By entering our tournaments, you agree to the Fighting Game Code of Conduct
